SUNON EF40202B2-E02U-AB9 24V axial fan

This SUNON EF40202B2-E02U-AB9 is a 40 x 40 x 20mm DC axial fan rated at 24V DC and 0.92W. It is intended as a direct replacement cooling fan for equipment that specifies this exact model suffix. The unit ships as a single fan with red and black 2-wire leads ending in a 2-pin connector.

Installation uses a 2-pin connector

Installation requires connecting the red and black 2-wire lead to a compatible 24V DC power source. The 2-pin connector shape, pinout and polarity must match the equipment header exactly. A common error is assuming interchangeability with similar-looking SUNON models that carry different electrical or connector specifications. Disconnect power before fitting the fan.

Verify model suffix voltage and mounting

Before ordering, confirm the complete model suffix EF40202B2-E02U-AB9 on the existing fan label. Check that the equipment supplies 24V DC and that the mounting hole pattern matches the 40 x 40mm frame with 20mm depth. Ensure the connector shape, pinout, polarity and installation orientation are identical to the unit being replaced.
